MERCURY
Since 1973
Besides low cost general purpose crystal clock oscillators Mercury also offers high quality and field-
proven application-specific oscillators for applications such as
♦ CPU, graphics, multimedia A/V clocks
♦ MPEG / DVD / HDTV clocks
♦ Laser engine pixel / set-top clocks
♦ Spread spectrum low EMI clocks
♦ Fast Ethernet and Gigabit Ethernet clocks
♦ NTSC / PAL encoder/decoder clocks
♦ PLL / synthesizer clocks
♦ Fibre channel and ADSL clocks
♦ OC-3, OC-12, OC-48 and OC-192 clocks ♦ SONET / SDH / ATM clocks
Mercury has the right oscillators to meet your specifications and your applications.

Start-up Time (Ts)
Note: Pad No. 1 is Tri-State by default for all SWO series. That is:
Pad 1
Connection
The output (pad No. 3) is active if no connection or voltage of 2.2V or greater is applied to pad 1.
The output (pad No. 3) is high impedance when voltage of 0.8V or lower is applied to pad 1.
Disable time is 150 n sec. max.; Enable time is 10 m sec. max.
±5 ppm per year max.
Aging
(1)Inclusive of 25°C tolerance, operating temperature range, ±10% input voltage variation, load change, aging,
shock and vibration.
